To 1f/ZZA whom it may con/cern: f

Be it known .that I, EMIL EINFELDT, of Davenport, county of` Scott, andState. of Iowa, have invented 'a new and useful Im.- provementinTractionWheels. of which the This invention relates to v and hasreference more particularly to the form and construction'ofthe tractioncleats,

and their vmanner of application tothe wheel 'c The invention consistsin complementary cleats, embodying each a baseflange adapted to beseated and secured tothe rim'of the Wheel, and a vertical fiange or webtoserve as a traction surface, the said cleats being so applied that thevertical flanges or webswill conjointly forma continuous and uninter-vptedl traction surface extending zigzag. around the-rim.

The invention consists also in the details of I construction andVcombination of parts hereinafterl describedandclaimed.

' In the laccompanying drawingsa-Fil l is a side elevation of a portionof a w Fig. 2 is a top plan view of the samepartly in section. Fig.-'3is a transverse section on.

theline a-a of Fig. `2. Figs. 4 and 5 are side elevations of two of thecleats detached,y showing their relative formsby which theyl are adaptedto coperate in accordance with' my invention. Fig. 6 is a planview of aportion ofthe rimI of a wheel, showin ,the traction cleats applied in amodified an different manner.

Referring to the drawings:-#1`2,j3, etc., represent my improvedtraction'cleats each in the form of a length of commercial vanglesteelha'vinga base flange A and anupright web or flange B, the baseflange being adapt-- ed tolrest on and be secured to the of the wheel,while the uprightdlange serves as a l'-trac1'.-ion rib or surface. Thesecleats are ap- 'plied to the, rim in' such manner and-in such .relativearrangement, ,that conjointly: the vertical flanges will :present anuninterrupted i and continuous 'traction rib or'.l surface `extending4zigzag around`.'the lw'heelrim.` As

"shown, the cleats extend' obliquely at relative angles, the base,flanges being overlapped v 1 ofthe cleats', each cleat has its "in orderthat the-vertical flange of one cleat may be brought close, up'to andform an angular continuation ofthe vertical e-of the next cleat.` Intheoverlapping of t e ends traction lwheels,

asefflange at.

fone end overlying -the base flange of one of its adjacent cleats, whilethe opposite end of its base flange underlies the base flange of its'other adiacent cleat. This arrangement is clearly illustrated in Fig.2, Where it will'be -seenwthat the forward end (assuming fonthepurposes'of. description that the wheel is traveling to the right) ofcleat `2 rests-upon and overlies the real; end 'of cleat 3 in advance,while the rear end of cleat 2 underlies and extends beneath the forwardend of cleat '1 at the rear. A

In order that in the arrangement described the upper edges of thevertical flanges will vvbe,

on the same level, that is flush with eaxli" the ends, I form the baseflange of each cient side to receive .the' base flange 'ofthe cleatuplon which it is seated, the result .being n that W en the cleats areassembled and the blend or socket portion of each. rests on. the basefla e of the\next cleat, the n per edge ofthe vertical fiange of thesockete cleat willbe at the same-u level or flush with and will adjointhe u per edge of the 'vertical .flange of the `next c eat. Thisconstruction is clearly'r illuswhich they areassembled and cooperate onthe rim *of the wheel; 'Anya a propriate means may be employed, such ashy the use of rivets, for firmiyattachingthe base fianges to the wheelrim, but I have shown and I prefer toutilize for this purpose, thevspokes of :the wheel, which are extended'througli the vof the'. cleatsand headedfdown thereon to seyticularly in Fig. 3..-

Referring to Fig. 2, it be observed that conjointly by the uprightflanges, extends a the vertical flanges intersect. This I contmted inFigs. s, und 5,v where if. win be and left, by reason. of the peculiarmanner in Wli'eel rim and through the overlapping ends c ure the partstogether, -as illustrated par' the continuous traction rib or'surfaceformed.

slight distance outward at the points where Sider desirable feature, inthat the tractive effect is increased. In order that this effect may bemore pronounced, the construction vshown in Fig. 6 may be employed,Where. it Will be seen that the cleats are extended. be-

yond their points ofintersection nearly to the edge of the rim.

' While I prefer to form the socket or bendl in the base flange of thecleat, in order to preserve the same height or level of the tractionsurface as described, it Will be'understood that this'is not essential,for good ref sults may he obtained by omitting these depressions andforming the traction cleat of the same crossesectional form throughout.

. Furthermorait is not absolutelyessential although preferable, that thecleats be` arranged rightand left in themanner shown, because goodresults'may be obtained by other arrangements provided that the trac.

tion surface formedl conjointly by thevertical 'flanges Will extendzigzagvand continuously around the Wheell rim. l Having thus describedmy lnvention, what I claim iszl.' In combination Withya Wheel rim,trac-- tion cleats eachcomprising a base flange andan uprightflange,said cleats extending diagonally With their base flanges overlapping atthe endsfand fastened to the rim `of the Wheel. i

' 2L In combination with a wheel rim, traction cleats, each comprising abase flange and an upright flange, said cleats'extendingl di- .agonallywith' the end of'the base flange 'of and having the other end of itsbase flange lextended beneath the base flange of its other ries oftraction cleats appliedl thereto and I adjacent cleat. j l

4. In comblnatlon with a Wheel rim, a se-` each comprising a baseflangeand an upright flange, said cleats extending .diagonally and each havingits base flange formed lin its uni der side at one end ywith a socket orbend adapted to 'receive the base flange of the adjacent cleat.

5. In combination with a wheel rim, a series of' traction cleats appliedthereto diagof nally, and each comprising a base flange and an uprightflange, the baseflanfy of one cleat being seated at one end on the Ivaseflange of one of its adjacent cleats, and extendin at its oppositeendbeneath the base flange o its other adjacent cleat, and each of saitcleats, where it underlies theend of the other, being extended beyondthe point of intersection.

6; In combination with a Wheel rim, 4a series of traction cleats appliedthereto diagonally and each comprising a base fiange rest ing on theWheel rim and an upright flange, each cleat being seated at oneextremity on the hase flange of the next cleat, with its end albuttingagainstthe upright flange of said c eat. l

v7. In combination with thevhub, s okes andi-im, traction cleats applieddiagona y to the rim With their ends overlapping,the saidv spokes beingextended outward through the rim and through the overlap ing vends ofthe cleats and acting to secure tli place. 4

8. In a traction Wheel, a series of' complementary traction A'cleats orelements, each comprising a base flange adapted to rest on and besecured to. the rim of the Wheel, and

an upright flange ada ted to form a traction rib, a portion of said ceats having a socket or bend formed 1n the base fiange at one end, andthel remalnder of fsaidcleats having a similar socket or bend formed intheir hase'- flange at theopposite end.
